Central helix bending in crystal form 1. (a) Conformational change of Glu84 is linked to the loss (yellow) of a hydrogen bond between Asp80 and Glu84 (blue). The straight conformation is shown in cyan and the bent conformation is shown in green. (b) 2Fo − Fc density for Glu84 in the bent chain contoured at 1σ. |
